Catwalk Mezzanines
Catwalk mezzanines are elevated walkway networks that connect equipment, work areas, and levels across a facility — providing safe overhead access and circulation without consuming floor space below. Where a full mezzanine deck adds a floor, a catwalk system adds guarded pathways: routes to service overhead equipment, cross over production lines and pipe racks, connect mezzanine levels, and reach utilities and instrumentation mounted at height. Modular Solutions engineers each catwalk from structural aluminum with a 40mm round handrail system, routing the walkway to your access points and clearances while holding OSHA guarding criteria and stairway geometry for the stairs and landings that serve it. Grated or serrated decking sheds debris and, in open designs, lets light through to the floor below. Because the structure bolts together rather than welding, catwalks install around existing equipment and reconfigure as the facility changes. Crossovers, branches, and multi-level connections build a complete elevated circulation network tailored to your plant. For facilities that need safe, permanent overhead access and circulation — to equipment tops, utilities, and between levels — catwalk mezzanines deliver an engineered walkway network that keeps personnel safe and floor space clear.
What Are Catwalk Mezzanines?
A catwalk mezzanine is an elevated walkway network that connects equipment, work areas, and levels across a facility, providing safe overhead access and circulation without consuming floor space below. Rather than a full deck, it adds guarded pathways to service overhead equipment, cross production lines, and reach utilities at height.
Modular Solutions engineers each catwalk from structural aluminum with a 40mm round handrail system, routing the walkway to your access points and clearances and integrating stairs and landings per OSHA criteria. Because it bolts together, the catwalk installs around existing equipment and reconfigures as the facility changes.
Key Features
Engineered around your space, load, and workflow — not a catalog template.
Elevated Circulation Network
Guarded walkways connect equipment, levels, and work areas without consuming floor space below.
Overhead Equipment Access
Routes to service equipment tops, utilities, and instrumentation mounted at height.
Crossovers & Branches
Cross production lines and pipe racks and branch to multiple access points.
Open or Solid Decking
Grated decking sheds debris and lets light through; solid decking where required.
Full Guarding
40mm round handrails, 42-inch guardrails, and toe boards engineered to align with OSHA 1910.29.
Bolted & Reconfigurable
The aluminum structure installs around existing equipment and reconfigures as the plant changes.
Common Applications
Configured for the specific space and access demands of your facility.
- Overhead Equipment Service - Walkway access to equipment tops, motors, and drives at height.
- Production-Line Crossovers - Guarded routes crossing over conveyors and production lines.
- Pipe Rack & Utility Access - Walkways serving overhead pipe racks, cable trays, and utilities.
- Inter-Level Connections - Bridges connecting mezzanine levels and elevated areas.
- Instrumentation & Monitoring - Access to elevated gauges, sensors, and control points.
- Facility Circulation - Safe overhead pedestrian routes across the operation.
Benefits
What a purpose-engineered mezzanine delivers on the plant floor.
- Keeps floor space clear while adding overhead access.
- Safe permanent access to equipment tops and utilities.
- Connects levels and areas with guarded walkways.
- Open decking options let light through to the floor.
- Reconfigures with your plant because the bolted frame adapts.
- Corrosion-free aluminum that needs no repainting.

Why Choose Modular Aluminum Mezzanine Construction
Modular aluminum mezzanine systems bolt together without welding and reconfigure without cutting — giving you a purpose-engineered elevated structure today that adapts through every layout change, capacity increase, and facility move without scrapping steel. Built from structural aluminum with integrated guardrails, stairs, and a 40mm round handrail system, the structure will not rust, flake, or require repainting, presents a clean professional appearance, and ties directly into our stair, platform, catwalk, and guarding ecosystem. It is lighter than steel — reducing floor and foundation loading and easing installation with minimal disruption — faster to relocate, and engineered and manufactured in-house in Auburn Hills, MI so the mezzanine fits your space, load, and workflow exactly rather than forcing your operation to fit a catalog.
Design & Engineering Considerations
How our engineers approach each mezzanine project.
- Access mapping - We map the equipment, utilities, and levels the catwalk must reach and connect.
- Routing and clearance - The walkway is routed to hold clearances over equipment and lines while keeping travel efficient.
- Structural design - Supports, spans, and decking are sized for pedestrian and transport loads.
- Access integration - Stairs, ladders, gates, and landings are designed into the network.
- Adaptability - Modular connections let the catwalk extend and reconfigure as the plant changes.
Safety & Compliance Considerations
Every mezzanine is engineered to align with OSHA 1910.29 guardrail criteria and relevant IBC mezzanine provisions; installed compliance is verified with your safety authority and local code official.
- 40mm round handrails, 42-inch guardrails, and toe boards engineered to align with OSHA 1910.29 along the full route.
- Grated decking selected to shed debris and, where open, provide visibility.
- Stair and ladder geometry engineered to align with OSHA 1910.25 and ladder criteria.
- Self-closing gates at access points and open ends.
- Clearances over equipment and lines engineered and verified with your safety authority.

Frequently Asked Questions
Common questions about catwalk mezzanines design, load capacity, and compliance.
What is a catwalk mezzanine?
It is an elevated walkway network that connects equipment, work areas, and levels across a facility, providing safe overhead access and circulation without consuming floor space below. It adds guarded pathways rather than a full deck — ideal for servicing overhead equipment and crossing production lines.
How is a catwalk different from a full mezzanine?
A full mezzanine adds a floor level for storage or work, while a catwalk mezzanine adds guarded walkways for access and circulation. Catwalks route to equipment tops, utilities, and between levels using narrow elevated paths instead of a large deck.
Can catwalks cross over production lines?
Yes. We design crossovers that carry personnel safely over conveyors, pipe racks, and production lines with engineered overhead clearance, guarding, and stairs up and down.
What decking is used on catwalks?
Open bar grating is common because it sheds debris and lets light through to the floor below; serrated aluminum or solid decking is used where a closed surface is required. We select the decking for the environment and use.
Are catwalk mezzanines OSHA compliant?
They are engineered to align with OSHA 1910.29 guardrail criteria and 1910.25 stairway geometry, with 40mm handrails, 42-inch guardrails, and toe boards along the route. Installed certification is verified with your safety authority.
Can the catwalk network be extended later?
Yes. The bolted aluminum structure extends, branches, and reconfigures with hand tools as your equipment and access needs change.
